[0002]
[Prior art]
As a conventional image pickup apparatus of this type, for example, there is a structure as shown in FIG. 24A is a front view and a side view of a conventional imaging apparatus, and FIG. 24B is a perspective view of the side view. In FIGS. 24A and 24B, 2 is an imaging lens, 101 and 102 are lens barrels, and 13 is a package. The package 13 is box-shaped and has a cavity structure inside, and the imaging element 3 having the light receiving surface 3a is mounted in the cavity portion. Here, it is electrically connected to a circuit pattern portion integrally provided in the package 13 by wire bond mounting (not shown) or the like, and is further sealed by the translucent plate 4. The lens barrel 102 is fixed to the package 13 with an adhesive (not shown) or the like, and is assembled by the lens barrel 101 and a screw portion (not shown). The focus adjustment of the imaging lens 2 is configured such that the lens barrel 101 and the lens barrel 102 can be adjusted by a screw portion (not shown). In such a conventional imaging apparatus, the subject information is collected by the imaging lens 2 and imaged on the light receiving surface 3 a portion on the imaging element 3. The subject information imaged on the light receiving surface 3a is photoelectrically converted and output as an electrical signal.
[0003]
[Problems to be solved by the invention]
Since the conventional imaging apparatus is configured as described above, the direction in which the imaging apparatus is facing in order to be able to confirm in what state the captured image is captured in the monitor frame with a digital camera or the like. It is necessary to be positioned on the opposite side of the monitor unit that displays the captured image. On the other hand, a mobile phone or the like equipped with an imaging device may be used for transmitting and receiving captured images through a communication line of a mobile phone. When capturing a self-portrait and transferring data, surrounding subjects, for example, subjects in a facing direction Two types of usage are conceivable, such as when imaging and transferring data. Therefore, in the imaging device mounted on the mobile phone, the self-portrait and the imaging in the facing direction are desired. However, since the conventional imaging device can only capture subject information in one direction as described above, both the self-image and the facing direction are provided. In order to take an image, it has been necessary to mechanically rotate the imaging apparatus itself so that it is directed toward the subject to be imaged.
[0004]
However, in a portable device typified by a cellular phone, an inferior use state that is different from that of a normal electric device, such as dropping or pressing, occurs daily. Therefore, it is not preferable to provide a mechanical operating unit such as a rotating unit on the design from the viewpoint of structural strength. In addition, when the imaging device is not mechanically rotated, when imaging in the facing direction, the imaging device-equipped device itself needs to be directed toward the subject, but the image is displayed on the display unit of the mobile phone in that state. The state of the captured image cannot be confirmed, and for example, it is difficult to adjust the subject to be positioned at the center of the screen. Such a problem has been described on the assumption that the mounting of the imaging device is mounted in the same direction as the liquid crystal display unit of the mobile phone, but it is possible to mount the imaging device in the facing direction in advance. . However, in this case, the same problem occurs when taking a self-portrait. As a means to solve these problems, it is possible to mount a plurality of imaging devices for imaging in both directions, but it naturally increases in cost, and in portable devices and the like, the size is increased. Such as an increase in weight, it may become an important problem that may reduce the value of the product as a portable device.
[0005]
Therefore, one imaging element, two imaging lenses, and a light reflecting component such as a prism mirror are used, and either one of the imagings can capture subject information in two different directions by reflecting the optical path with the prism mirror. A device is conceivable. However, in this case, either the imaging direction is switched to one by an external shutter or the like, or the bidirectional subject information is always imaged so that the subject information in the different subject directions does not interfere with each other. It is necessary to provide a structure such as a threshold plate to separate and to separate subject information in two directions inside the imaging apparatus. In the former case, the external shutter is switched mechanically by the user, but an external shutter switch or the like appears on the design of the device, and the mobile phone etc. However, there is a problem of structural strength in the equipment. In the latter case, since the threshold plate is a small part and high-precision assembly is required for optical region separation of subject information in two directions on the image sensor by a threshold plate or the like, Feasibility is difficult.
[0006]
Accordingly, the present invention has been made to solve the above-described problems, and an image pickup apparatus that does not require switching of the image pickup direction by an external mechanism and that can pick up images in different directions with one image pickup device is obtained. It is another object of the present invention to provide a mobile phone incorporating this device.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
A first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 and FIG. 2 are a perspective view of an imaging apparatus according to the present invention and a developed view of its outer portion, respectively. 1 and 2, reference numeral 1 denotes a lens mount, 2 denotes an imaging lens incorporated in the lens mount 1, and 201 and 202 denote imaging lenses for imaging in different directions. Reference numeral 3 denotes an image sensor. Here, the internal structure and operation principle of the imaging apparatus according to the present invention will be described with reference to FIGS. 3A and 3B are cross-sectional configuration diagrams of the imaging apparatus according to the present invention. 3A and 3B, 1 is a lens mount, 3 is an image sensor, 6 is a prism mirror, 201 is an imaging lens for imaging in the normal direction with respect to the image sensor 3, and 202 is a prism mirror. 6 is an imaging lens for taking an image in the horizontal direction with respect to the image sensor 3, 3 a is a light receiving surface configured on the image sensor 3, 4 is a translucent plate, 5 is an imaging lens 201, This is a threshold plate for separating the optical area of optical information in different directions obtained from the image lens 202. Reference numeral 701 denotes an optical path in the normal direction from the imaging lens 201 side, and reference numeral 702 denotes an optical path from the horizontal line direction from the imaging lens 202 side.
[0025]
As shown in FIG. 3B, the subject information from the horizontal direction is reflected by the prism mirror 6 and imaged on the light receiving surface 3 a on the image sensor 3. At this time, the light flux in the optical path 701 and the light flux in the optical path 702 are separated from each other by the threshold plate 5 and therefore do not interfere with each other. The optical information imaged on the image pickup device 3 is photoelectrically converted at the light receiving surface 3a and output to the outside as an electric signal. The electrical circuit portion and the electrical connection between the image pickup device 3 and the electric circuit portion are provided. Examples of the method include a wire bond method and a flip chip bond method. Here, FIGS. 4A, 4B, and 4C are explanatory views for explaining a process of placing the threshold plate 5 between the light-transmitting plates 401 and 402 divided on the light receiving surface 3a of the image pickup device 3. FIG. It is. As shown in FIGS. 4A, 4B, and 4C, the threshold plate 5 is configured so as to be sandwiched between the translucent plates 401 and 402 divided.
[0026]
By the way, when the imaging apparatus of the present invention is mounted on a device such as a mobile phone, it is desired not to provide a mechanical external shutter mechanism because of the structural strength requirements of the devices. Therefore, the imaging lens is not switched by the external shutter, and the subject information from the imaging lenses 201 and 202 is always imaged on the image sensor 3, but either optical information is obtained by processing on the device side such as a mobile phone. Whether the image is displayed on the liquid crystal monitor of the mobile phone is switched by software, and is selected by a key operation by the user.
[0027]
As described above, the principle of the imaging apparatus in which the light area is separated by the threshold plate 5 and imaging in at least two directions using one imaging element 3 and at least two imaging lenses 201 and 202 has been described. The region between the light receiving surface 3a of the image pickup element 3 and the threshold plate 5 cannot be used as an effective light receiving region because light does not enter. Therefore, the threshold plate 5 is preferably as thin as possible. However, if the threshold plate 5 is a small and thin part, the configuration shown in FIG. FIG. 5 is a cross-sectional configuration diagram for explaining the configuration of a lens mount incorporating the imaging lenses 201 and 202 of the imaging apparatus according to the present invention. In FIG. 5, a threshold plate portion 501 that is continuous with the lens mount 1 is integrally formed with the threshold plate 5 shown in FIG. The threshold plate portion 501 can be molded with an extremely thin thickness of 0.1 mm to 0.2 mm. 6 (a) and 6 (b) are cross-sectional configuration diagrams showing states before and after the image pickup device 3 of the image pickup apparatus according to the present invention is attached to the lens mount 1, respectively. As shown in FIGS. 6 (a) and 6 (b), the translucent plates 401 and 402 divided corresponding to the optical paths by the imaging lenses 201 and 202 are imaged so as to sandwich the threshold plate portion 501 of the lens mount 1. The element 3 is configured to be assembled.
[0028]
As described above, according to the imaging apparatus of the first embodiment, the threshold plate portion 501 that is an optical region separating unit is formed integrally with the lens cloak 1, so that, for example, the imaging apparatus in two directions Assembly becomes easy and productivity can be improved. When the lens mount 1 is a molded product and the molding material has a light shielding property, low thermal expansion, impact resistance, low moisture absorption, electromagnetic shielding function, etc., when mounted on a device such as a mobile phone. In addition, the performance of the imaging device can be stably operated even in the environment where these portable devices are used. Further, the translucent plate 5 may be a component having optical characteristics for the purpose of blocking the infrared light region or ultraviolet light, or for improving the light transmittance. Since it is not necessary to arrange them, it is possible to reduce the number of parts and production man-hours, and to have the function of these optical characteristics while reducing the size of the imaging device.
[0029]
Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIGS. 7A, 7B, and 7C are a perspective view showing an imaging apparatus according to the second embodiment, a perspective view when the lens mount 1 and the imaging device 3 are disassembled, and the lens mount 1 and the imaging device, respectively. FIG. 8A and 8B are a front view, a side view and a rear view of the lens mount 1, respectively, and an enlarged view in which the rear view is enlarged. FIGS. 9A and 9B are a rear view of the lens mount 1 and a front view of the imaging device 3, respectively. In FIGS. 7, 8, and 9, 1 is a lens mount, 201 is a normal imaging lens, 3 is an image sensor, and 3 a is a light receiving surface provided on the image sensor 3. Reference numerals 801 and 802 denote image circles of subject information imaged by the imaging lens 201 and an imaging lens (not shown). The image circle 1 corresponds to the imaging lens 201, and the image circle 2 corresponds to the imaging lens 202. Reference numeral 501 corresponds to a hatched portion in FIGS. 8B, 9 </ b> A, and 9 </ b> B, and is a threshold portion configured integrally with the lens mount 1. In the imaging apparatus according to the second embodiment, as shown in FIGS. 7C and 9A, the image circles 801 and 802 are positioned diagonally to the light receiving surface 3a on the light receiving surface 3a. Thus, the arrangement of the imaging lenses 201 and 202 is configured. In FIG. 9B, since the imaging lenses 201 and 202 are arranged so that the image circles 801 and 802 in the light area on the light receiving surface 3a of the image pickup device 3 are linear, the lens mount 1 is mounted. The threshold portion 501 needs to be configured in a longer range than that shown in FIG.
[0030]
In the second embodiment, the threshold part 501 of the light region separating means is formed integrally with the lens mount 1. However, as described above, the threshold part 501 is required to have a thin structure, and if the range is long, molding is performed. Formation becomes difficult. According to the second embodiment, since the imaging lenses 201 and 202 are arranged so that the two image circles are positioned diagonally on the light receiving surface 3a on the light receiving surface 3a of the image pickup device 3, the thin-walled structure is provided. The range of the threshold part required for this can be set to a very small length, and the productivity when integrally forming the lens mount can be improved.

Embodiment 3 FIG.
Next, Embodiment 3 of the present invention will be described with reference to FIGS. FIGS. 10A and 10B are a rear view of the lens mount 1 of the imaging apparatus according to the third embodiment as viewed from the back, and an explanation showing a state when the translucent plates 401 and 402 are incorporated in the lens mount 1. FIG. 11A and 11B are perspective views of the lens mount 1 as seen from the side. 10 and 11, the same reference numerals as those in the first and second embodiments denote the same or corresponding parts, and thus the description thereof is omitted. In FIG. 10A, reference numeral 1a denotes a contact portion for determining the accuracy of the incorporation balance of the translucent plates 401 and 402 when the translucent plates 401 and 402 are incorporated into the lens mount 1.
[0032]
Since the translucent plates 401 and 402 are assembled in contact with the contact surface 1a of the lens mount 1, they can be accurately positioned perpendicular to the optical path 701 as shown in FIG. When the translucent plates 401 and 402 are disposed to be inclined with respect to the optical path 701, the optical path is determined on the optical path from the imaging lens 201 to the imaging device 3 due to the relationship between the space portion having a different refractive index of light and the translucent plate portion. There is a case where the image becomes uneven in the entire area, and the unevenness in resolution may occur in the imaging apparatus. However, in the imaging apparatus according to the third embodiment, the translucent plate is not tilted with respect to the optical path, and is disposed exactly orthogonal to each other, so that the performance of the imaging apparatus can be stabilized and easily assembled. it can.
[0033]
Embodiment 4 FIG.
Next, Embodiment 4 according to the present invention will be described with reference to FIGS. FIGS. 12A and 12B are rear views when the lens mount 1 of the imaging apparatus according to Embodiment 4 is viewed from the back, and FIG. 13 is a perspective view when the lens mount 1 is viewed from the side. In FIG. 12 and FIG. 13, the same reference numerals as those in the third embodiment indicate the same or corresponding parts, and the description thereof is omitted. In FIG. 12A, reference numeral 1b denotes an adhesive reservoir for disposing and fixing the translucent plates 401 and 402 to the lens mount 1. FIG. 12B is an explanatory view showing a state in which the translucent plates 401 and 402 are arranged on the lens mount 1 and bonded with the adhesive 9.
[0034]
According to the imaging apparatus according to the fourth embodiment, as shown in FIG. 13, as shown in FIG. 13, excessive adhesive does not adhere to the bonding interface portion between the translucent plate 4 and the lens mount 1, and the translucent plate is bonded. Since it is prevented from being tilted by the agent, it is not uniform over the entire optical path due to the relationship between the space part having a different refractive index of light and the translucent plate part on the optical path from the imaging lens to the imaging element. It is possible to prevent the occurrence of problems such as uneven resolution, stabilize the performance of the imaging apparatus, and easily assemble.
[0035]
Embodiment 5. FIG.
Next, Embodiment 5 according to the present invention will be described with reference to FIG. FIG. 14 is a cross-sectional configuration diagram seen from the side surface of the lens mount 1 in the imaging apparatus according to the fifth embodiment. In FIG. 14, the same reference numerals indicate the same or corresponding parts, and thus description thereof is omitted. As shown in FIG. 14, the internal structure of the lens mount 1 forms a tapered portion 1c. The tapered portion 1c forms a tapered portion 1c at a threshold portion extending to the vicinity of the light receiving surface so as to divide the light area of the light receiving surface into two. That is, in the optical path from the imaging lens 201 to the imaging device, the tapered portion 1c is formed so that the opening on the imaging lens 201 side is small and the opening on the imaging device side is large. In the optical path from the light refracted by the prism mirror 6 so that the light enters the imaging element in the vertical direction to the imaging element, the opening on the imaging lens 202 side is reduced and the opening on the imaging element side is increased. Thus, the tapered portion 1c is formed.
[0036]
As described above, in the imaging device according to the fifth embodiment, since the tapered portion 1c is formed inside the lens mount 1, when the lens mount 1 is molded, a molding die and a lens mount that is a molded product are used. The mold release of 1 can be improved, thereby making it easy to form a threshold part which is a thin part. Further, since the tapered portion 1 c is formed inside the lens mount 1, the inner wall portion of the lens mount 1 can be “slip-shaped” by a molding die, and irregular reflection of light within the lens mount 1 can be achieved. Therefore, it is possible to prevent quality degradation such as flare of the imaging apparatus.
[0037]
Embodiment 6 FIG.
Next, a sixth embodiment of the present invention will be described with reference to FIGS. FIG. 15 is a perspective view of the imaging apparatus according to Embodiment 6 as viewed from the side.

Reference numeral 1d denotes a screw portion provided on the lens mount 1, and reference numeral 10a denotes a screw portion provided on the lens holder 1d. Reference numeral 1e denotes a reference portion for assembling the lens mount 1 in contact with the image sensor 3. The other parts denoted by the same reference numerals are the same as or equivalent to those of the above-described embodiment, and thus description thereof is omitted. As shown in FIG. 16, since the reference portion 1e of the lens mount 1 is assembled in contact with a portion other than the light receiving surface 3a of the image sensor 3, the relative positional accuracy in the height direction with the image sensor 3 is assembled with high accuracy. .
[0038]

That is, the lens holder 10 of the imaging lens 201 is not provided with the screw portion 10a, and the corresponding lens mount 1 is not provided with the screw portion. The imaging lens 201 and the lens mount 1 are bonded and integrated in advance with an adhesive 9. As described above, the focal point of the imaging lens 201 is determined by the molding accuracy of the lens mount 1 because the reference portion 1e of the lens mount 1 and the imaging device 3 are brought into contact with each other and assembled. In the imaging apparatus according to Embodiment 6, the lens focal length is 5 mm or less, and the lens mount molding variation of the size can be ± 0.01 mm or less, and the adhesion variation between the imaging lens 201 and the lens mount 1 is varied. Even in consideration of the above, it is possible to make it sufficiently within the range of freedom of focus adjustment.
[0039]
As described above, in the imaging apparatus according to Embodiment 6, it is not necessary to adjust the focus of the imaging lens 201, which facilitates production of the imaging apparatus. Here, the adjustment in the focus direction has been described with no adjustment of only the imaging lens 201 in the normal direction, but the focus adjustment in the horizontal direction may also be made unadjusted. Further, the adjustment of the imaging lenses 201 and 202 is not adjusted, and an adjustment mechanism for both the imaging lenses 201 and 202 may be provided. Even in this case, since the relative positional relationship between the lens mount 1 and the image sensor 3 is stabilized, the adjustment range of the imaging lenses 201 and 202 can be narrowed, and the time required for the adjustment can be omitted. is there.
